font-family:Arial'>I am trying the new USB dwc-otg Synopsys driver on my powerpc
405ex board. I am using the kernel 2.6.30.3 from denx git (head 2.6.30
stable 2009-09-04 snapshot). Previously I was using the USB driver from
2.6.25 kernel. The driver was unstable and was only working when I
enabled some debug prints. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am moving to the new kernel to get improvement on that USB
driver. However, I have some problems with it. My problem is that probe
function is never called (dwc_otg_driver_probe). The driver init call is
done and I can see the debug print “dwc_otg: version 2.60a 22-NOV-2006”
but no more call (n.b. I enabled all debug print). Initialisation is done
in probe function, so, my usb dwc_otg controller is not initialized. In
theory, when module is inserted, init is called (dwc_otg_driver_init). This
init call, register the driver (platform_driver_register) and, in this
registration, configured the probe function to call (dwc_otg_driver_probe). But
as I said, probe is never called.<o:p></o:p></span></font></p>
